2018 DODGE DURANGO Wheels Problems

THERE IS A RUBBING/GRINDING SOUND FROM THE FRONT RIGHT TIRE GOING 55+MPH. THE HEATING & COOLING IS SHUTTING OFF AND NOT TURNING BACK ON. RADIO SCREEN IS HOT TO THE TOUCH

69000 MILES, CHECK ENGINE LIGHT CAME ON. CODES P0440 WAS THROWN 2X. I ALREADY REPLACED PURGE VALVE AT MY OWN COST. I ALSO INFORMED DODGE. THEY WON'T FIX IT UNLESS I PAY FOR DIAGNOSIS. WHICH I ALREADY HAD ONE DONE. ALSO HEADLIGHT BULB DROPPED AT 38K MILES AND I INFORMED DODGE AND MECHANIC. SHE SAID I DIDN'T HAVE THE WARRANTY ON IT AND THEY WOULDN'T REPLACE UNLESS I PAID FULL COST

I PURCHASED A VEHICLE FROM STG AUTO GROUP IN GARDEN GROVE AND NOTICED A WEEK LATER WHILE MY CAR WAS PARKED IN MY DRIVEWAY, THAT THERE WAS A LARGE SLASH ON THE FRONT PASSENGER TIRE ON THE WHEEL WALL WITH AN ORANGE PAINTED CIRCLE AROUND IT. I WAS TOLD BY A PROFESSIONAL THAT THE DEALERSHIP NOTICED IT, AND CIRCLED THE SLASH BECAUSE WAS MEANT FOR IT TO TO BE CHANGED TO PASS THE SAFETY INSPECTION TO BE SOLD. THE SERVICE DEPARTMENT DID NOT REPLACE THE TIRE BEFORE SELLING AND NOW IS A SAFETY HAZARD. THE DEALER IS REFUSING TO REPLACE THE TIRE.
